1
Brown
Loop Voltage In
Optional for increasing compliance. Input range: +16V to 36Vmax
2
Black
Current Out
Will drive 20mA into 625Ω without external boost voltage. See
Table 2-3
.
3
White
Voltage Output
Specified for load resistance ≥1kΩ. Recommended load resistance: 100kΩ to minimize voltage drop due
to wire resistance in connecting cable.
4
Blue
Isolated Ground
Connection required for current and voltage output
